Benefits of technology
The present patent provides a system and apparatus for irrigating a surgical site during an electrosurgical procedure. The system includes a hand piece with controls for adjusting the flow of irrigation fluid and suction, a valve cassette with valves for controlling the flow, and a hardware control module for controlling the valves. The system also includes an irrigation tube for delivering fluid and a suction tube for withdrawing fluid and smoke. The apparatus includes an elongated housing, a multilumen tube with irrigation and suction tubes, and electrical wiring with first and second controls for adjusting the flow of irrigation and suction fluid. The apparatus also includes a valve cassette with valves for controlling the flow, and a hardware control module for controlling the valves. The technical effects of this patent include improved irrigation control and efficient fluid management during electrosurgical procedures.

Embodiment Construction
[0023]Embodiments of the present disclosure are described below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail.
[0024]The foregoing disclosure describes embodiments with reference to a monopolar laparoscopic surgical instrument. However, principles of the present disclosure may be utilized in a bipolar instrument as well as suitable open instruments.
[0025]An electrosurgical system and method to be used to perform cautery procedures, hemostatis, and other suitable procedures are provided. The system provides irrigation and / or suction (e.g., a vacuum line), which may be performed contemporaneously with the electrosurgical procedure or after the procedure is complete. In some embodiment, the irrigation fluid may be used to cool the electrosurgical cautery electrode to reduce eschar build-up, modify tissue effect, and / or prevent ina...

A system and apparatus for irrigating a surgical site during an electrosurgical procedure are disclosed. The system includes a hand piece having an elongated housing connected to a multilumen tube extending proximally from the housing and having an irrigation tube for delivering irrigation fluid, a suction tube for withdrawing irrigation fluid, and electrical wiring, a first controls for adjusting flow of irrigation fluid within the irrigation tube and second controls for adjusting flow of irrigation fluid within the suction tube. A valve cassette is connected to the multilumen tube, which includes an irrigation valve configured to control the flow within the irrigation tube and a suction valve configured to control the flow within the suction tube. A hardware control module controls the irrigation valve and the suction valve based on control signals from the first and second controls.
Description
BACKGROUND[0001]1. Technical Field[0002]The present disclosure relates generally to an apparatus and method for performing laparoscopic electrosurgical procedures, and more particularly, to an apparatus for controlling suction and irrigation cycles during laparoscopic electrosurgical procedures.[0003]2. Background of Related Art[0004]During electrosurgery, a source or active electrode delivers energy, such as radio frequency (RF) energy, from an electrosurgical generator to a patient and a return electrode or a plurality thereof carry current back to the electrosurgical generator. In monopolar electrosurgery, the source electrode is typically a hand-held instrument placed by the surgeon at the surgical site and the high current density flow at this electrode creates the desired surgical effect of ablating, cutting or coagulating tissue. The patient return electrodes are placed at a remote site from the source electrode and are typically in the form of pads adhesively adhered to the ...
